Several days ago wrote a post called A New Bot In Town and I suggest you read that too, not only because
is one of the more trustworthy people on Steemit, but because he knows infinitely more about these things than I do. I will say that he wouldn't push something that is a scam. With
seeming to have developed narcolepsy Steemit is in dire need of another reputable upvote bot (and I'm in no way implying here that there aren't others on here). Moreover, I keep getting notifications from the
notification widget telling me he's awake when he's not... of course the money is always refunded, but it becomes increasingly irritating.
I'm not exactly sure about how works other than it "spins" on Wed and Sun. I'm not certain if how much you put in is cumulative or not... I suggest you read
's post and
's posts as well. I can say that I received a "spin" from them and it seems to have boosted my post by around $3.00. I also put in for a spin for
. I don't know if it helped him or not. Anyway, I like the concept and will continue to "feed" the bot. I encourage you to check it out for yourself.
